</div>
<div class="panel panel-default">

<i class="fa fa-edit"></i>
<b class="panel-title"> Contact Info. </b>
</div>
<div class="panel-body">
<div class="form-group">

<input asp-for="userContactDetail.ContactDescription" class="form-control" />
</div>
<div class="form-group">

<select class="form-control" asp-for="userContactDetail.ContactTypeId" asp-items="@(new SelectList(Model.contactTypes, "Id", "Name"))"><option value="-1"></option></select>
</div>

</div>
<div class="form-group">

<input asp-for="userContactDetail.ContactExtension" class="form-control" />
</div>
<div class="row">

Primary
</label>
<label class="col-sm-6 form-group">

</div>
<div class="form-group">

<div class="form-group pull-right">

<button id="btnCancelContact" class="btn btn-sm btn-danger"><i class="fa fa-ban"></i> Cancel</button>
</div>
</div>
<div class="form-group panel-body">
<div class="table-responsive">
<table class="table table-striped table-bordered table-hover" id="tblContacts" name="tblContacts">

</div>
</div>
<button type="submit" id="btnUpdateProfile" class="btn btn-success">Update Profile</button>
this is how I'm submitting my form
$('#btnUpdateProfile').click(function (e) {
e.preventDefault();
var formData = $("#formUpdateProfile").serialize();
$.ajax({
url: "/Admin/UpdateProfile",
type: "POST",
data: formData,
processData : false,
contentType: false,//'application/x-www-form-urlencoded; charset=utf-8',
dataType: "json",
success: function (data) {
toastr.clear();
if (data.status == "Success")
{
toastr.success("User updated sucessfully.");
return;
}
else
{
toastr.error(data.message);
return;
}
},
error: function () {
toastr.clear();
toastr.error("Something went wrong. Please try again.");
return;
}
});
When I submit my form, I always get lstAttachments empty in my controller while other data is perfectly correct. I've tried many solutions like
Added a for loop and changed .serialize() to .serializeArray() for object reference in a .each() to append to the FormData. but it didn't work for me. Then i tried this way;
var fd = new FormData();
var file_data = object.get(0).files[i]; //get file data
var other_data = $('form').serialize(); // get form data
fd.append("file", file_data);
but again, no help to resolve my issue... Can someone explain what I'm missing? Any Kind of help will be appreciated.
Update
This is my form tag
<form asp-action="UpdateProfile" method="post" id="formUpdateProfile" enctype="multipart/form-data">
